MOLD FOR ARTIFICIAL STONE.

To all whom it may concern:

Be it known that I, THnonoun V. Ganissr, citizen ot the United States,residing at the city and county of San Francisco and Sta-te ofCalifornia, have invented new and useful Improvements in Molds t'orArtificial Stone, &c., or" which the following is a specification.

My invention relates to mold-boxes, and particularly such molds as areused in torinin g concrete blocks, bricks, or other like articles.

One of the objects of my invention is to provide a simple, sectionallyformed mold, in which are to be made suitable artilticial stones, suchas are usually made of a mixture of concrete and other' materials, andare usually reinforced in the ordinary way, with iron rods or wiresspread through the plastic material.

Another object is to provide ay mold-box ot' such length that it may bereadily divided into separate sections ot` suitable lengths so as toallow the molding of several separate or individual stones or blocks inthe one box, and providing means for adjusting the sections intosuitable lengths.

Referring to the accompanying drawings, Figure l is a perspective viewotl the moldbox. F ig. 2 is'an end view of the same. F ig. 3 is a rearview. Fig. 4 is a front view of the box. Fig. is a cross sectional'view.

In the embodiment of my invention as actually employed I provide a backmember or section 2 having on its upper' edge al suitable metallic stripor perforated l'lange 3 which is firmly secured to the back member. Thisback member is made orsuiiicient thickness, and may be constructed ofwood, or other suitable material, so that suitable grooves A may bechanneled throughout its length so as to form any desirableornamentation on the surface of the stone or block to be made.

The mold is particularly useful in the formation of steps, sills,intels, mullions and the like, which are usually made up in largenumbers, and of course one article or stone,

such as a step, would be made of the same design.

The bottom member is detachably secured to the rear member by suitablelocking screws G, and brace hooks 7, and is provided along its outeredge with a vertical perforated liange metal strip 8. The strips 3 and Sproject more or less toward eachother Specification of Letters Patent.Patented Sgpt, 28, 1909, Application led October 12, 1908.

and beyond their contiguous members; and the space included between theparts 2 5 and the projecting flanges of 3 8, as shown in Fig. l, forms amold space to be filled with suitable material which is tamped so as toinsure the formation of a solid coirpact mass. The locking screws 6 arepreferably rigidly set in the bottom member 5 otl the mold-box, and inassembling the sections the back 2 is slipped over the screws 6 whichproject from the rear edge of the bottom Suitable locks or lockinghandles 9 are then screwed up on the screws 6 tightly against the back2, thus maintaining the back at an approximately right angle to thebottom member. The bracing members 7 are secured at suitable pointsalong the length of the back 2 and bottom 5, and are bent angularlytoward each other, and have hooks l0 and eyes ll so that they areintorloeked, and maintain the parts in rigid position when the lillingmaterial is being tamped.

At l2 is shown a removable wall or partition plate adapted to be settransversely across the mold-box at any desirable point, by means oflocking-pins 13, insertible through holes la made in the strips 3 and S.

The bottom-plate 5 may be provided with suitable foot-'pieces l5 alongits length, and thereby supported clear ot' the ground or platform onwhich it may be used. Obviously, one of these mold-boxes may be made inlengths, say, of 2O t'eet more or less, and as many ot' the dividingwalls l2 as desirable, may be set at suitable points along the mold-box,and when the material is then filled into the mold-box, it will beapparent that a series oit' stones will be formed simultaneously, allhaving similar shape and of the same mixture.

It will be noticed that the mold is made practically of only twosections, the back Q and the bottom 5, and when it is necessary toremove the molded block or stone from the box, the back 2 is removed byunscrewing the locks 9, and the stone may be lifted from the bottoni 5.An important advantage in this simplicity ot' construction, lies in thefact that when it is desired to make blocks of ditlerent contour ordesign, it is only necessary to change or replace the back 2 withanother having the desired contour, or moldingl groove 4. Manifestlythis groove 4 can be made of numerous designs, all of which will lendthemselves readily to the molding of the stone. The inner surfaces ofthe member 2, rnd the bottom 5, afe'preferably made extremely smooth;and cleansed after each operation,V and in this manner the Work ofsmoothing or polishing the finished article is much reduced.-

"Wlien actually using the mold `for form-Y ing shapes, a suitable lining15 of paper', cloth, or equivalent, is first laidl in against the sidesof the mold to insulate the artic'ial composition from thev mold vandpermit the molded shape to be readily removed.

Having thus described my invention, What I 'claim and desire to secureby Letters Patent is A'mold comprising a bott-om member and a sidemember, WithA means for detaohably' securing them together, said membershaving anges on their outer edges, which flanges project toward eachother, said lianges and bottom and side members in# cludlng it moldspace, said flange members having p'erfor'ations, and an adjristablepar? titi'on fitting in the mold space, with.` mea-ns passingthroughi-saidperforatioiis 1nd erigaging with said partition to hold thesame .A

1n place. l

In testimony whereof I have hereunto Set my hand in presence of twosubscribing,
